FYI: GitHub master updated to version 0.1.4, demo (http://demo-ritzy.rhcloud.com/) updated to the same version. New DESIGN (https://github.com/ritzyed/ritzy/blob/master/docs/DESIGN.ado...), INSTALLATION (https://github.com/ritzyed/ritzy/blob/master/docs/INSTALLATI...), and API (https://github.com/ritzyed/ritzy/blob/master/docs/API.adoc) docs. Demo has new controls that use the API. A bunch of bug fixes and improvements esp. around some more complex collaboration stuff e.g. operations that overlap with remote selections and cursors as one example.
